IMPROVEMENT IN STRAW BAND ATTACHMENTS FOR GRAIN-BINDERS.

Specification forming part of Letters Patent No. 212,200, dated February11, 1879 application filed July 17, 1878.

To all whom it may concern:

Be it known that I, GEORGE DAVIS, of Milford, in the county of Oaklandand State of Michigan, have invented an Improvement in Straw-BandAttachments for Harvesters, of which the following is a specification:

The nature of my invention relates to certain new and usefulimprovements in devices designed to be attached to harvesters, which areprovided with devices for binding the gavels or sheaves before beingdischarged from the harvester-table, so constructed as to spin or twistthe straw bands as they may be required in the use of the harvester; andthe invention consists in the novel construction and combination of thevarious parts, as more fully hereinafter described.

Figure l is a perspective view of my device, taken from the front. Fig.2 is a rear elevation of the same. Fig. 3 is a vertical section throughthe center from side to side.

In the drawings, A represents a frame-work and table designed to supportthe operating parts of the device. B is a cylinder, terminatin g in aninverted cone, 0, and is provided with a flange, D, which rests upon androtates with friction-rollers E, suit-ably journaled at equal distancesapart in the tabletop of the frame A.

Within the cylinder B are secured the smaller cylinders F, their lowerends being beveled, as shown at a, and opening into the cone 0, thisbeing .necessary to give more room within the cone to receive and handlethe contents of the cylinders. This cone 0 projects downward through asuitable opening in the top of the frame A, and terminates in a shortspinning-tube, G, through which, at equal distances apart, areadjustably inserted the spinning-teeth I. This adjustability may besecured in any desired manner which will allow the teeth to be projectedwithin the tube G as much or as little as varying circumstance mayrequire.

Secured to the outer face of the cone 0 are the teeth H, by means ofwhich this part of the cone acts as a bevel or miter wheel engaging withthe miter-wheel J, secured to the shaft K, by means of which and anysuitable power the proper motion may be communicated to the cylinder B.

Upon this shaft K is also secured the pinion L, which engages with thegeared wheel M, secured upon shaft N, in suitable bearings, and uponthis shaft is also secured the drawing-roller O, the opposite end of theshaft being provided with a driving-pinion, P, which, engaging with thepinions Q R, gives motion to said pinions and to the drawing-rollers ST, which are suitably journaled in the frame for that purpose.

The pinion R engages with the pinion U and gives motion to the roller V,all said rollers and pinions being so arranged that O and S form onepair, and T and V form another, one of each pair only rotating in thesame direction. Upon the same vertical line, and in line with the centerof the spinning-tube, theserollers are grooved, asshown in the drawings,and for the purpose hereinafter described.

In practice the operation of this device is as follows: The smallcylinders F are filled with straw, preferably the stubble end beingpresented downward, and a small quantity thereof forced downward throughthe spinning-tube, twisted by hand, and inserted through the grooves inthe rollers T V, the former of which should have a slight vertical adjustability. This beiu g done, motion should be given to the machinethrough the shaft K and the various gears connected therewith, and ashereinbefore described. This motion, by means of the teeth I, spins ortwists the straw passing through the spinning-tube G, and the positionof said teeth regulates the size of the band, as may be required, suchband being drawn through the spinner by the operation of the rollershereinbefore described, and a greater or lesser number of such rollersmay be employed, as is necessary to perform the work.

If desired, the spaces between the small cylinders and between them andthe cylinder B may also be filled with straw, and the number of thesmall cylinders may be increased or diminished from those shown in thedrawings, so long as the spirit of this part of the invention, which isto preserve the straw in a straight and vertical position, is notdeparted from.

What I claim as my invention is--.

1. In a device for making continuous straw cone 0, spinning-tube G, withteeth I, and a bands, and in combination with abattery of system ofdrawing-rollers, constructed and cylinders, as described, the cone 0,terminatarrangedsubstantiallyas describedand shown. in g in thespinning-tube Gr the latter of which 1 is provided with laterallyztdjustable teeth I, GEORGE DAVIS substantially as and for the purposesset forth.
